Revolubly supported by the supplemental stationaryframe 13 is a member 17, having an arm 18 projecting therefrom and asmall handle 19, byfwhich the vmember may be turned. The member 17 has'fixed thereto avvorm 20, so that' the Worm is turnedA axially Wheneverthe handle flO . by the handle 19.

the same manner that the Worm 20 is moved previously mentions whichenters an an nular space in the revoluble member 17 the latter isprevented from longitudinal 'movementv in either direction, but 'canonly move I rotatably. In a similar Way the revoluble member 21 isprecluded from any endwise movement by the engagement of its arm 22 andWorm 211 With the ends of the revolublel member 17. Around theworm 20and 24 I arrange a pair of what 1 shall term wormcasings 26v and 27which telescope Within one another and Within the tubular frame 5, so asto be independently movable longitudinally but not rotatably therein. Inorder to preclude rotative movement of the Wormcasings, I may use a keyor any equivalent device, such as the pin 28, fixed to the tubular oasin5 and extending through alined slots in eac of the tubular Casin s 2627. 26" and l27 indicate portions of t e Wormcasings 26 and 27, to whichthe rods 29 and 30' ma be attached. The rods 29 and' 30 exten downwardthrough the tubular iame 5 and are operatively connected to thecontrolling-shafts 31 and 32 in any convenient It Will be seen that thetubular frame 5 is stationary under all circumstances and constitutes asupport for all the other parts. The steerin Wheel or head 1 maybemanipulated at t e leasure of the' operator, by which the revo ublesleeve 2 is turned upon the tubular franie to steer' thevehicle in anydirection. 'Under these circumstances, however, the supplementalstationary frame 13 remains immovable and with it each of the controllin-handles 19 and 23. At an time the handle 19 may be moved, Whic swingsthe Worm 20 through a part of a revolution, so that the Worm-casing 26is moved up and down Within the tubular frame 5, so as fo manipulate theoontrolledshaft 31. In like manner the handle 23 may be turned at anytime to move the controlled shaft 32, and it is obvious that either ofthese things may be done simultaneously or at different times Without inany. Way aliecting the back and forth over the index-ring 15 the Worm 24will be turned in B virtue of the cap V1-3,

'said supplemental stationary frame,

other or the manipulation orfcontrol of the steering Wheel or head.

l am aware that it is not broadlynew to secure the control 'of amotor-vehicle from the steering Wheel or head; but I revard the features"of construction herein set Iorth as accomplishing all the desiredpurposes with Aa minimum number of parts and the highest eiiioiency ofoperation.

A feature of my invention relates to the possibility oi independentmovement of .the

Worm-casings 26 and 27 and the controller' rods 29 and 30. It will beobserved that the rods 29 and 30 pass through openings in the bottomwalls 26 and 27 of their respective Worm-casingsand are held by nuts 29and 30. In normal operation the rods 29 and 30 are both under tension,`(by vgravity or in any-other suitable Wa so that they take any movementapplie to the Worm-casings. Should it happen, however, that either ofthe rods has an independent governor-con trol, as is accomplished in mypending application, Serial rods may rslide upward through theperforated lates 26 and 27 and accommodate the in ependent control ofthe governor. this way the vehicle is simultaneously controllable lfromlthe governor and from the steering-head.
